KETTLE FOR TRYING OILS.

Specicaton forming part of Letters Patent No; 22,152, dated November 30,1858; Reissued September 12, 1876, No. 7,805.

To all 'whom t may concern:

Be it known that I, J. L. ALBERGER, of Bualo, in the county of Erie andState of New York, have invented certain new and useful Improvements inKettles or Boilers for Trying Oils, Fats, &c.; and I do hereby declarethe following to be a full, clear, and exact description of theconstruction and operation of the same, reference being had to theaccompanying drawings, making a part of this specication, in which-Figure l, represents a perspective view of the boiler, and its support,with an apparatus attached, for condensing the foul gases or vaporsthrown olf. Fig. 2, represents a longitudinal vertical section throughthe apparatus, leaving t-he connecting pipe, and worm pipe of thecondenser in full. Fig. 3, represents a transverse vertical sectionthrough the boiler and its supporting bed.

Similar letters of reference where they occur in the several figures,denote like parts of the apparatus, in all of them.

My invention relates to the construction and arrangement of a boiler ortank, surrounded by a steam acket, or having steam introduced in itsinterior, and made 4to revolve upon its bed or cradle, for the purposeof emptying it of its contents, and used with or without a condensingapparatus, the object being to boil, or try fats, oils, &c., by thedirect, or the indirect action of steam, as will be hereafterparticularly pointed out.

To enable those skilled in the art to make and use my invention, I willproceed to describe the same with reference to the draw ings.

A, represents a metallic, or otherwise, bed, at each end of which arepillar blocks B, B, the tops of which are rounded out, to suit theperimeter of the boiler, or boiler heads that are to turn thereon. Inthese pillar blocks B, B, are arranged double flanged friction rolls l,2, 3, set in the circumference of a circle, corresponding to that of theboiler heads.

rlhe boiler or tank C, is cylindrical, but having that part of it C',through which the opening from the exterior is made, slightly swelledout, or flaring, to cause the oil, or fats, to run out when said boileris turned over. The boiler C, may be surrounded by a steam jacket D, soas to leave steam-way a all around its sides and ends, eXcept just wherethe cover E, that closes the manhole or opening comes.

riihe cylinder heads F to the jacket or outer cylinder D, are madestrong, and pro` ject from 2 to G inches from the cylinder. Thesecylinder heads rest on the friction rollers 1, 2, 3, in the pillarblocks B, B, which allows the boiler to be readily turned over foremptying it of its contents. There are hollow journals Z), b, aiiixed toeach of the cylinder heads F, but the boiler is not supported on thesejournals, its weight rests upon the friction rolls 1 2, 3. The journalsare hollow for the purpose of admitting steam not only into the steamway a, between the tank and jacket, but also if so preferred to the pipeo, which leads into the tank, and thus furnish steam in direct contactwit-h the material being boiled-the steam pipe c, being open at itsinner end, for this purpose. 'lhe red arrows in Fig. 2, show how thesteam enters. The gas or vapor which rises from the boiling mass, risesto the upper part of the boiler, and is carried off by the pipe d, (asshown by the blue arrow, in Fig. 2) through one of the hollow journalsand thence to a condenser G, where the vapor is condensed and thus allthe foul smell arising from the boiling of animal fats, avoided.

'I "he object in making the length of the cylinder horizontally, greaterthan its height, is first, to keep its top low down, and thus save theelevating of the material to the top of the boiler; secondly, to preventa heavy column'of fluid matter over the steam pipe c, which wouldrequire a heavy head of steam to force it through and into the boiler,against this column; thirdly, it rests and turns more readily upon itsbearings.

The advantage of swelling out that portion of the boiler about theman-hole, is that when the boiler is turned over to be emptied, all thecontent-s will run out, as that part is the lowest, when turned over.

The parts e, c, where the steam enters, and where the vapors pass out,are made tight by packing in the usual way, while a steamjoint ispreserved so that the boiler may turn without twisting the pipes thatlead into, and outof ite-said pipes being supported in stationary bossesor sleeves f, supported by the braces 0, 0. The water of condensationbetween the boiler and acket, may be drawn off by a Cock i, Fig. 1; andthe steam may be let olf at the top by a cock h, Same ligure; and athird one g may be so arranged as to draw off the oil or :tats from theinterior tank, Without opening the man hole for that purpose, and thiscock may be placed at or above thecenter of the tank. When the tank isused Without the jacket, the cocks are arranged accordingly.

Having thus fully described the nature and object of my invention, WhatI claim therein as new and desire to secure by Let-- ters Patent is Ahorizont-ally placed cylindrical boiler o-rk tank, surrounded by a steamjacket, or having the steam admitted directly into it, when said boileror tank is capable of being turned over in its cradle and have all itsforth.
